A quantum logic gate is a basic quantum device that operates on a small number of quantum bits or qubits. A unitary matrix -- a square matrix of complex numbers -- represents the quantum gate. A 2nx2n ...

A single MXene-based optical gate switches between seven Boolean logic functions via voltage, enabling trainable photonic networks for AI tasks. (Nanowerk Spotlight) All-optical logic platforms are ...

The digital world offers many advantages over its analog relatives, the use of boolean logic among them. Some of the functions, like NOT, OR, and AND are fairly straightforward and line up nicely with ...

Why it matters: For decades, scientists have dreamed of building computer chips that use light instead of electricity to process information. While our current silicon chips are incredibly fast, ...
